De-Glitching Solutions
by Dick Crowe
Below are a list of suggestions they may help you diagnose solutions to your glitching
problems. If you have a solution to offer, please e-mail me and I'll add it too the list.
Try keeping your motor, receiver and speed control at least 4 inches from
each other.
Keep your wiring from criss crossing all over the place and away from the motor where
possible.
Make sure your antenna wire exits the hull as soon as possible (I put my receiver in the
back right corner). Don't cut it or wrap the excess up in the hull. Make it long! This may
not look cool but is very effective.
Make sure you have the appropriate capacitors and/or possibly a shotky diode on the motor
(check the manufacturers recommendations on the speed control and motor for the correct
ones).
Check your brushes for extensive wear and the commutator on the armature that it isn't all
black. If either of these conditions exist have the motor repaired. You can do it yourself
if able or send it in.
If you’re using a receiver with BEC, try a 6 volt receiver battery pack or instead.
Try shielding the receiver. Use lagging tape (aluminum sticky backed tape) or foil to
cover the whole receiver. Make sure the shield touches nothing else, and covers all
exterior casing.
Make sure all electrical connections are good and use good quality connectors.
The simple process is always elimination. Beg, borrow and steal other parts to try with
the boat. When the problem goes away, or reduces, you may have found the component, or a
contributing factor.
The financial method: Get Hitec's new Dual Conversion FM receiver.
Finally, keep your radio gear dry. If you don't have a radio box, wrap your receiver in a
little paper towel and double bag it. If you do have a radio box, do it anyway, it's cheap
insurance. Check it often for leaks and remove it at the end of the day. The bottom line
is that receivers that get wet don't always make a 100% come back.
There are a few other tricks but these are the biggies in my estimation.
